public function OgExampleSelectionHandler::buildEntityFieldQuery in Organic groups 7.2

Overrides OgSelectionHandler::buildEntityFieldQuery().

This is an example of "subgroups" (but without getting into the logic of sub-grouping). The idea here is to show we can set "My groups" and "Other groups" to reference different groups by different logic. In this example, all group nodes below node ID 5, will appear under "My groups", and the rest will appear under "Other groups", for administrators.
